Authorities are investigating the "suspicious death" of a young woman in a home on Country Club Road in Bethlehem Township, Pa.

"It is being treated as a suspicious death at this time," Northampton
County District Attorney John Morganelli said shortly after leaving the home tonight. "We are handling it as a
crime scene because we don't know exactly what happened yet."

The homeowner returned today to find a visitor had died in his home, township police Chief Daniel Pancoast said. Police were called to the home about 1 o'clock.

"Due to her age, the coroner was contacted, and the district attorney," he said.

Pancoast said he does not believe the woman is a township resident but declined to provide further details. Morganelli estimated the woman was in her 20s.

Other issues than just her age led authorities to investigate it as a suspicious death, but Morganelli said he could not get into any specifics.

"We have to let the police do their work," Morganelli said, adding autopsy results will also shed light on the death.

Northampton County Coroner Zachary Lysek could not immediately be reached. Morganelli said he was still at the home as night fell.
